The LIGO Scientific Collaboration and the Virgo Collaboration report:


We have re-analyzed LIGO and Virgo data around the time of the compact

binary coalescence (CBC) candidate S190510g (GCN 24442). Parameter

estimation has been performed using LALInference [1] and a new sky map,

LALInference.fits.gz, distributed via GCN Notice, is available for

retrieval from the GraceDB event page:


https://gracedb.ligo.org/superevents/S190510g


For the LALInference.fits.gz skymap, the 90% credible region is 1166 deg2.

Marginalized over the whole sky, the a posteriori luminosity distance

estimate is 227 +/- 92 Mpc (a posteriori mean +/- standard deviation).

This is the preferred sky map at this time.

this alert, refer to the LIGO/Virgo Public Alerts User Guide
